Yes, if you are talking about the normal carbon composition types having colour codes. But there are some non-linear types too.
It is a linear device if it is not a wire wound resistor. These become non linear to AC at high frequencies because of their inherent inductance.
A: THE WORD IS LINEAR. yes it is not a very linear device as a function of current
a resistor
A passive device is a diode resistor coil and so forth it perform no enhancement to the circuit or act on it.
A device which operates(or function) only in one direction is called unidirectional (or unipolar) device
It is a linear device if it is not a wire wound resistor. These become non linear to AC at high frequencies because of their inherent inductance.
linear and non-linear resistor
YES it is linear. It is a passive device classified as linear however as frequency increases its behavior will change.

In electronics, bidirectional device is device which can be used by both directions like resistor. It does not effect on characteristics of device if we change the terminals of that device.
There is no formula it depends on the device. If the device is linear it can be ascertain but if it a non linear then it becomes quite complex

A varistor is a variable resistor. It changes value dependent on the current draw and operates by changing its value as the resistor's temperature changes. For instance, during turn-on of a device, the resistor heats up causing the resistor to change it's value, thereby limiting the inrush current to the device. Once the initial start-up current is reduced and the device is operating normally, the resistor cools down and changes value again.
